To all whom it may concern Be it known that I, WILLIAM H. EYNON, a citizen of the, United States, residing at Cleveland, in the county of Cuyahoga and have invented certain new and useful Improvements in Methods of Making Chain Mesh, of which the following is a specification.

y invention relates to improvements in methods of making chain-mesh such as shown and described but Patent No. 1,086,810, for improvements in machines for making chain-mesh issued and dated February 10, 1914, of which patent this application is a divisional part.

As disclosed in my said patent my improved method of making chain-mesh consists in (1) rotating and projecting a wire helix in a common plane, (2) coils thereof, (3) moving the cut ends of the coils into closed links, and (4) moving and holding the same in a convolutions of the next rotating jecting helix. 7 V

he machine described and claimed in said patent is herewith illustrated and described for the purpose of illustrating a machine which may be used for carrying out my improved method as well as illustrating the nature and steps to betaken in the improved method of making chain-mesh.

housing-frames or standards 2, each of said housing-frames being provided with the a usual bearing guide-ways containing lower stationary bearings 3 and upper movable bearings 4. The lower or stationary bearings 3 are providedwith a and the upper or movable bearings 4: are provided with a vertically movable or sec- 0nd shaft 6. The shafts 5 and 6 are geared together by means of gear-wheels 7 at one end and are provided at their other end with Wire feed-rolls 8. Each of said feedrolls is providedabout its periphery with a pair of wire-receiving bearing grooves 8, said feed-rolls being interchangeably mountshaft so that should one of the bearing grooves become worn the feed-roll may be reversed so as to bring the companion bearing groove into use. As a means for ad ustmg the upper or second alternately thrown into and out of gear with end with a fixed shaft 6, and particularly the tension of the upper feed-rolls upon the lower feed-rolls, tension springs 9 are interposed between the movable bearings 4: and tension adjusting bolts 10, adiustablv mounted in the upper portions of the housings 2, in a well-known manner.

.As a means for driving the feed-rolls 8, the driving-shafts 5 are provided with loose bevel-gears 11, adapted to drive suitable clutch mechanism, hereinafter described, said bevel-gears meshing with a second set of bevel-gears 12, carried upon a nally extending driving shaft 13, mounted in suitable bearings 14, on the bed 1. The shaft 13 is driven by means of a gear-wheel 15, meshing with a pinion 16, carried upon one end of a main driving shaft 17, mounted in suitable bearingslS', at the rear of one of the bearing ends of the frame. The main driving-shaft 17 is provided at one drivingpulley 19 and an idle or loose pulley 20, said'pulleys being adapted to carry a belting communicating with any suitable and convenient source of power. r

The wire feed-rolls 8 are adapted to be the driving mechanism, as hereinafter described, and the wireis adapted to pass through suitable guides 21, in front of each pair of feed-rolls, said guides acting to direct the wire in proper position between bearing grooves, and 'asjth'e' wire passes between the bearing grooves 8 of the feedrolls the latter force the wire spiralforming'dies or coiling mandrels 22 at the rear. The coiling mandrel is provided on its periphery with a longitudinally extending groove 23, adapted to receive the wire as fed from the feed-rolls8, said groove terminating in a spirally arranged portion 23, so as to form,

casing shell or supporting sleeve 24:, the necessary spiral path for the wire as the same isforced therethrough by means of the feedrolls. The supporting sleeve is removably mounted and secured in a bearing-lug 25,-

by means of a set-screw 26. The coiling mandrels 22 may be keyed or otherwise re-' movably' secured within the supporting sleeves 24, as desired. I

The bearthreaded shaft being revolved by means of ing bracket plates 55, together with the ata pinion 48, meshing with a gear-wheel 49, tached guide-plate 56, may be supported in carried by the adjacent driving-shaft 5. A any suitable and convenient manner, as by carriage block 50 is slidably mounted upon attaching brackets 57 and as a means for 25 the carrier shaft 45, and is adapted to be evolving the gripping rollers 54, for elevatlongitudinally driven on the carrier shaft ing the formed links and holding the same 5, by means of a depending portion 50 in proper position for receiving the coils or having a threaded face held in engagement convolutions of the forming helix as the latwith the threaded timer shaft by means of a ter'passes through the helix groove or guide- 30 counter-weighted lever 51. As the carriage way 28, and through the meshes or openings block travels along the carrier shaft it'is o the most recently formed rings as inditravel to engage the bevel portion 44 of the wheels 58 may be mounted upon one of the trip latch and depress the latter whereby the bracket-plates 55 (see Fig. 8), said wheels 85 same disengages the shifting lever 42, and having their teeth adapted to engage gearthe lever spring 43 throws the jaw-clutch teeth or cog-pins 59 on the ends of the gripout of engagement thereby stopping the reping rollers, motion being transmitted to spective feed-rolls at the point desired. The said toothed wheels by a ratchet-wheel 60, operator then moves the operating lever 40 provided with a pinion portion 61, meshing 40 to one side until one of the stops 52 is with one of the toothed wheels 58. The brought into engagement with the adjacent ratchet-wheel 60 is adapted to be iven an ed portion l this movement reciprocating intermittent motion by means of a hand t e cutting members in opposite directions, lever 62, provided with a pawl 68, for cowhereby the guide cutting teeth 29 are operating with the ratchet-wheel 60. The 45 thrown out of their registering position to length of the throw of the hand-lever 62 is out the intermediate coils or convolutions of adapted to be limited and regulated b the helix. Fig. 4 shows the intermediate pomeans of adjustably-inounted stop-plates 64, sition of the'cutting teeth 29, justafterhavwhereby the elevation of the chain-mesh or ing severed the intermediate coils or convolink fabric, and the most recently formed 50 lutions of the helix. This position of the rings from the throat portion 27 of the guide cutting teeth takes place during the guide members 27, may be regulated for the intermediate travel of the operating lever purposes hereinbefore referred to. The 40, and a further movement of this lever 40 outer or front gripping roller 54 is carried carries the guide cutting teeth to a further in depending brackets 65, carried upon ac0n- 55 position, whereby the adjacent cut ends of necting bar 66, extending between the the co1ls or convolutions are brought into bracket plates, said depending brackets beregistry with each other forming the rings ing adapted to press the outer or front grip- 3 of the chain mesh. As the elasticity or ping roller 54 toward the opposite or cospring in the rings will have a tendency to operating roller by means of coiled springs 60 retract the adjacent cut ends when relieved 67, on the bar 66, and coiiperating with the of the pressure of the cutting teeth, the brackets 65, in an obvious manner, whereby throw or reciprocation of the cutting teeth the coiiperating gripping rollers 54 are re may be regulated so as to carry the adjacent volved toward each other to engage and eleends slightly past the registering position so vate the formed links 53 of the fabric be @5 that w en the cutting teeth are retracted to low, it being understood that the initially 46, so that the or returned to its initial position on the carrierv shaft 45, as indicated in the drawings. l

formed row of links or rings upon the commencement of the formation of the fabric may be manually elevated and held-in position for receiving the projecting Wire helix as hereinafter described, and then manually. elevated between the gripping rollers 54, aftext which the fabric may be elevated at intervals by the hand-lever 62, in the fabric forming operation. After the, elevation of the formed rings, as abovedescribed, the opposite" feed-rolls are brought into operation to project the wire helix through the guide members 27, in an opposite direction and through the openings or meshes of the formed rings, as hereinbefore described. Before shifting the respective shifting-lever the counter-weighted lever 51, of the carriage block 50, is elevated to bring the threaded face of the depending portion 50? out of engagement with the threadedtimer shaft carriage block may be shifted An adjustable stop block 68, on the carrier shaft45, is vadapted to be adjusted for lime iting the movement of the carriage block on the carrier shaft &5.
